We first evaluate STML on standard benchmarks for metric learning [1]}, [2]}, [3]}, where it largely outperforms existing unsupervised learning methods.
Surprisingly, sometimes it even beats some of supervised learning models using the same backbone network as shown in Fig. REF .
Beyond that, its efficacy is demonstrated on two benchmarks for semi-supervised metric learning [4]}, where it substantially outperforms previous work as well.
